The present invention relates to improvements in oil burners and more particularly to that type of burner in which the combustion of the oil is facilitated by the admixture of steam.

A further object of the invention is to provide a burner of this character, having a body through which the fuel is fed and arranging the steam feed pipe within the body in spaced relation from the walls thereof, whereby to utilize the heat from the pipe in heating the oil, and forming the discharge end vof the steam .pipe into an atomizing nozzle and disposed immediately beneath the discharge mouth of the body of burner whereby to thoroughly atomize the fuel as the same is discharged from the burner.

A still further obect of the invention is to provide a detacha le mouth piece for the discharge end of the steam feed pipe as well as the fuel discharge portof the body, whereby to permit the removal and replacement of the mouth pieces when desired.

An additional Objectis to provide a pair of diverging extensions formed on the mouth piece for the fuel discharge port, serving to direct the atomized fuel outwardly at each side of the mouth piece, whereby to spread the fuel over a. relatively large area.

Another object is to provide a Vburner of this character of a simple and practical construction, which is eilcient and reliable iny performance, relatively inexpensive to manufacture and install in operative position and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the special construction and combination of the various elements comprising the invention, reference being had to the accompanying drawings, forming a part hereof, wherein:

Figure 1 is a top plan View.

Figure 2 is an end elevational view of the outer end of the burner.

Figure 3 is a similar view of the inner or discharge end thereof.

Figure 4 is a longitudinal sectional view therethrough.

A Figure 5 is a plan view of the mouth piece for the steam pipe with the mouth piece for positeend. A bore 8 is formed in the end of the body immediately beneath thefzfuel intake port 6 andl within which is inserted a steam feed pipe` 9 having its `inner'vv end threadedly received in a steam discharge port 10 formed at the opposite end of the body immediately beneath the fuel discharge port 7. The outer portion of the bore 8 is of an increased diameter as shown at 11, whereby to receive Va packing gland 12 formed on one side of a plate 13, attached to theintalre end of thebody by means of bolts 14 or the like.`

As clearlyillustrated inFigure 4y of the drawing, the steam pipe 9 is disposed in spaced relation from the walls of the body so that the heat of the steam passing through said pipes will be utilized to heat the oil within the body. Flanges 15 are formed at the sides of the discharge end of the body to which similar flanges 16 are secured by bolts 17, the fianges 16 being formed at the opposite sides of upper and lower mouth pieces 18 and 19 respectively. The mouth piece 18 is formed with a substantially rectangular shaped openin 20 communicating with the discharge port of the body and at the outer edge of saidv mouth piece is formed a pair of wings 21 extending outwardly at diverging angles from the sides of the opening 20. The under side of the mouth piece 18 intermediate its inner and outer edges is formed with an upwardly extending. recess 22 and formed of a width equal to the width of the opening 20. The underside of the forward edge of the mouth piece 18 is also formed'with a relatively shallow recess 23, communicating at its inner end with the recess 22 and constitutes an atomozing nozzle for use in a manner `as will be hereinafter more fully described.V The upper surface of the lower mouth piece 19 fits snugly against the under side of the upper mouth piece 18 and is secured thereto by bolts 24. The outer edge of the upper' mouth piece 18 is extended across the bottom of the space between the wings 21 and forms a base therefor. The inner end of the lower mouth piece is formed with a chamber 25, 1 communicating with the discharge port through which the steam pipe 9 is connected, the chamber 25 opening through the upper surfaceofthe lower mouth piece and communicating with the recess 22 formed on the upper side of the upper mouthpiece. It will be obvious from the foregoing and after an inspection of Figure l of the drawing, that vthe steam from the pipe 9 will enter lthe chamber 25, for discharge through the atomizer nozzle 23. Furthermore, it will 'be noted that the atomizing nozzle 23 isdisposedimmediately beneath the discharge-end of the fuel opening 20 o f the upper mouth piece and .upon being subjected vto the force of the steam leaving the nozzle will'be thoroughly atomized and forced outwardly from the inner endof the burner. The wings 21 at the sides of the fuel discharge opening will serve to spread the vatomized'fuel over a relatively large ,area as the saine is .discharged from the burner. It will be understood from the foregoing that thesteam fed Vinto the pipe 9 performs a double function, namely, for heating the oil contained in the body of the burner land atomizing the fuel as the same is discharged from the inner Aend .of the burner.

It is obvious from the foregoing that the invention is susceptible of various changes and modifications, without departing from the spirit or scope of the invention or sacrificing any of its advantgaes, and we accordingly claim all such forms of the device as covered by the appended claim.

What is claimed is:

ln an oilburner including a. body portion, a nozzle detachably mounted on one end of the body portion and comprising a. lower section and an upper section mounted on the lower section, thev upper section having its free end terminating inwardly o f the free end of the lower section, the upper section being provided with a longitudinal polyg: onal air pasage lextending from end to end thereof, diverging wings formed integrally on the forward end of vthe upper section on opposite sides of the air passage and ext-ending over the lower section, the upper section being further provided with a. recess in its lower side beneath the air passage and of a width substantially corresponding to the width of the air passage, the lower side of the upper section being still further provided with a comparatively shallow recess entend,- from the first named recess to the forward end of the upper section and constitutmg an oil passag'etherebetween,` and the lower section of the nozzle being. provided with an angular oil receiving chamber communicating with the rear end of the lower section and with the first named recess in the upper section in a manner to discharge oil thereinto.
